DUPLICATING MACHINE.'

Application filed May' 19,

ToaZZnwmmzt may concern.' Be. it known that I, ALBERT M, Avans, a citizen of the United States, residing at lutley, in the county of EssexV and Stateof` New Jersey, have invented certain new and useful Improvements iny .Duplicating `Malchines, of which the following isV a specification, referencebeinghad therein to the accompanying drawingwy .f l `My= inven'tionfrelatesfto improvements in duplicator. machines andl more? particularly has 'reference' to that typey of machinein Whichthe surface upon which the impression is taken and from Which duplicate `records are made is rotated in such a man-ner as jto takeupand print successi-ve sheets of paper from aystack, automatically depositingthe saine in. a-substantially flat-and uniform stack, the entire operation being practically automatic, except for two simple hand movementsi f l j In the accompanying drawings, I have illustrated in Fig. 1in side elevation partly. broken away and partly. in dotted .outline:a suitable form. ofduplicator machine. embodying anr application-` of my invention.` Fig. 2 isa plan View looking down-upon the, same. Fig..3 is a section o n thelinelf'of, Figi--y 2; ."Fg. v4is a) similar `view toFig..3,-. except-,that it shows the retaining rollein-` the position in Which yit rises to lift the sheet against the printing-roll, and Fig; `5 is a frontrelevation partly broken away`v illus uotius the Shoot gripping mooufl-uslu- Referring now more` particularly 'to Figs.'y l-to 4 inclusive, 6 indicates*thelegs lofthe machine upon which the frame?" is mounted as shown, and 8-91O indicate the transverse braces connecting the side frames 7. 11 indicates a suitable rack attached to the cross bar 12 at the opposite end of which corresponding with the position of the rack 11 is secured a guide bar 13. The rack 11 it Will be observed meshes With the pinion 14 pivoted in the frame 15, and the pinion 14 in turn meshes with the pinion 16, also rotatably secured upon said frame and which in turn engages the large pinion 17 mounted upon the axis 18 of the large roll. This large roll is provided With a semi-circular portion 19 over which the gelatinous strip 20 passes feeding from the roll 21 to the roll as shown, thus presenting a printing surface from the idlers 23 to 24 covering not less than half the entire circumference of the said roll 19.

By now lifting the bar 40 the top sheet is brought in Contact with the gelatinous surface 9.0 and adheres thereto, after which the finger piece 41 being pushed leftwardly causes the projection 43. extending from beneath theV tray 29, to ride upon the inclined and preferably resilient surface 44, thus bringing the roller 45 against the sheet now adhering to the gelatino-us sheet nas aforesaid. The next operation is to draw the sheet right- Wardly looking at Fig. 1, which automatically rotates the large cylinder, leaving the inked impression upon the sheet, and for the bar 50 which in turn is secured atthe inner end to the block 51 projecting from said standard 47 and upon said bar 50 is an extension coiled spring 52 which when the standard 47 is pushed lettwardly isrcompressed. By now rotating clockwise the handle 46 secured to the bar 53, said bar having a cam 54, the latter is rotated lifting the lower jaw 55 which coming in contact with rthe upper aw 56 though normally separated by the spring 57, grips the free end of the paper projecting beneath the lower roll 19 and by now gripping the hand rail 58 and pulling rightwardly looking at Fig. 1 the sheet is drawn beneath the roller which by contact with the web 2O transfers the impression rom'the roller to the sheet and the gripper remains in its leftward extended position against the compression of the spring 52 until the sheet finally releases from the gelatin web 20, thereby causing the gripping Adevice to iiy rightwardly, the han dle 46 striking the inclined side 58 of the hand bar 58 which thereby automatically throws the lever 46 upwardly or anti-clock wise thereby releasing the jaws and allowing the sheet of ,paper to fall between the side frames 7 where Vthe sheets stack in. a substantially flat and uniform manner and from which position they can be conveniently removed.

VUpon the tray 29 are side members 60 which may be moved in the direction of each other or may be separated merely toserve as a sort ot guide for the paper stacked upon the tray and the same applies to the plate 61 formed at the hinge of the pivoted arm 30. 62 indicate stops in the path of the rack 11 and guide bar 13.

From the foregoing it will be apparent that the relative position of the large cylinder and its driving mechanism may be varied by disengaging the rack 11 and pinion 14. lt will be readily observed that by lifting` the handle 58 when at its extreme rightward position, looking at Fig. 1, the entire frame including rack 11, guide bar 13, and cross brace 12, may be raised from driving engagement and the large gear 17 may then be rot-ated to the desired position before the .iframe is replaced in its driving position, thus permitting such adjustment of the parts as may be found desirable.

Oi course it will be understood that various modifications may be made in the construction and arrangement of parts without departing 'from the spirit of the invention as claimed.

l claimt ln a machine of the class described, means for engaging the ends ot sheets successively upon a printing roller, means for gripping and drawing the sheet beneath the roller and while in Contact therewith, andl means for releasing the sheet substantially simultaneously with its release from said roller, said means for engaging said sheets and said roller comprising movable tray upon which said sheets are stacked, and means for lifting said tray in the direction of said roller and in combination therewith a. sheet holding roller adapted to press said sheet against said first mentioned. roller during the entire period rof the printing operation, a rack and pinion mechanism for operating said printing roller, said mechanism being adapted to be moved in and out of engagement with said printing roller for varying its degree of rotation.
